Does my local hostname have to meet some kind of constraint?  For 
example, I chose "vandelay":

[bvitale@vandelay ~]$ cat /etc/hosts
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1       vandelay        localhost

Is my hosts file setup correctly?  If yes, then why am I getting errors 
like this in sendmail:

Aug  3 21:02:07 vandelay sendmail[10299]: My unqualified host name 
(vandelay) unknown; sleeping for retry

Please help - thanks,

Ben
